06DA825 7.5HP Efficient Semi Sealed Compressor
Optimized Cooling for Commercial Refrigeration
The 06DA825 is a 7.5HP 6-cylinder semi sealed compressor engineered for medium and low-temperature cold storage, quick-freezing rooms, and commercial display systems. Built with contoured pistons and precision-engineered Swedish steel valve plates, it reduces clearance volume and fluid losses during suction and discharge. This configuration maximizes overall thermal efficiency while ensuring steady refrigeration capacities under demanding continuous duty cycles.
Enhanced Lubrication and Motor Safeguards
To solve common operational risks like motor burnouts and rapid oil loss during frequent start-stop cycles, this semi sealed compressor features an advanced electrical insulation structure alongside a bidirectional high-flow positive displacement oil pump. An oversized crankcase oil sump prevents temporary starvation caused by liquid refrigerant migration, protecting vital bearing journal surfaces and significantly extending system uptime.
Smart Capacity Control and Flexible Operation
Additionally, this semi sealed compressor integrates a suction cutoff unloading system that allows 33% or 66% capacity regulation, maintaining substantially lower discharge temperatures than traditional bypass loops. Equipped with a heavy-duty suction filter and broad HFC refrigerant compatibility, it offers versatile integration into modern eco-friendly cooling installations.
